Need some help fellas

[KlanjacOFF]

Maybe I'm retarded but I cannot figure out a way to keep the crank from spinning while trying to take off the crank pulley bolt off. I tried putting a wrench on my flywheel bolt and wedging it between my engine stand but all that does is loosen the flywheel bolt. What techniques have you guys used? Heres some pics if that helps. I'm stuck on this right now, seems like even if I put the flywheel back on theres still not going to be anything to hold it in place.

[KlanjacOFF]

Another random question, what is this for on the transmission?

[StricNyne]

i think like gear oil breather

[240z4u]

Stick a breaker bar between two of the bolts and roll the motor over until the handle binds up on the engine stand.

Thats a trans breather.

find a big adjustable wrench and open it up so it can fit around one of the arms of your engine stand. on the handle end of the adjustable, lodge it so if you rotate the crank it just compresses the adjustable wrench into the arm of the engine stand (make sure it won't slip). tighten that flywheel bolt in as far as you can so it won't bend and so the clamping force holds the wrench along with the compression force.

or you can do it like 240z4u says, but that may be hard with how far the middle of the crank end sticks out..

I did just as 240z4u did.

i know on my 3000gt i have to use a spanner wrench(i think its called that) or at least it helps to break the crank pulley loose when im changeing timing belts.

[KlanjacOFF]

Thanks guys the advice helped. I found a long 3/8s extension and shoved it in between one of the flywheel bolts and the engine stand. Worked perfect. I didnt even need to use a breaker bar, but thats probably because I soaked that ***** in seafoam overnight. What puller did you guys use? I know Autozone does not carry a 2 prong puller, but I'm thinking the 3 jaw puller will get the job done.

Spanner wrench is the wrench used for adjusting coilovers

[StricNyne]

this tool fixxes everything

haha seriously i had hell torqueing my flywheel bolts to spec my friends had to hold it

[BoostFab]

like i suggested in another thread, slide in a prybar or crowbar between the two bolts and it will brace against the stand.

[gawdzilla]

to get the pulley off you kind of want to use something like this: http://www.matcotools.com/ProductImages/p522.jpg

don't use a 3 prong "claw" type puller, especially if this is the first time the pulley is coming off. it is probably stuck on there pretty good and chances are you are gonna bend up/break the lip of the pulley your claw is yanking on.

the crank pulley is threaded (figure out what size it is, i think it's m6 or m8) but go to home depot and buy some bolts to get the size right, then use the 2 prong puller to pull on those bolts.

True. Im not sure if all 3 prong pulley pullers are like this but mine attaches to the rear of the pulley so it does no damage to the item itself. Screw it and it comes off. Easy as that.

What I did was put the transmission in gear and just yanked the ratchet hard enough a couple of times to make it finally loose. I know your situation is different. Do you not have a air gun or anything like that? (probably not cause your asking us haha) This would make life so much easier. I suggest you get like a couple gallon one for around $50 and invest in it. Its nice to have for stuff like this.

impact to remove the bolt and the upper timing cover long allen bolts and a 2 washers with a crank pulley puller do wonders, its threaded for a reason.i have some bolts dedicated to this purpose as to not destroy the bolts from the timing cover.

[KlanjacOFF]

Werd

The FSM tells you the size for those two bolts so that'll make it easy to find at home depot. Looks like Advanced Auto might carry that two prong pulley, gonna go check tomorrow. It is on their website.

and so I can be sure, The crank pulley bolt stays in but 1 cm back, while you pull off the crank pulley. thats what it says, i think, in the FSM. sorry for the noobiness.

Are you talking to me? Yes I have air tools but when I went to use my impact gun it spun the entire assembly. That is why I had to wedge something into the flywheel bolts to keep it all from spinning. Don't know why that was, maybe my gun did not have enough torque, I think its rated at 346ft/lbs or so. Orrr maybe it was loosening the bolt because it was extremely easy to break loose with my ratchet.

[nizmo zilvia]

Strange. I used my friends air gun and never had a problem like that. In fact it was alot easier taking off the crank pulley and flywheel + clutch.

yes.. put the crank bolt back in without the big washer. make sure you remmeber the front/back orientation of the big washer.. the FSM has a picture. thread the bolt a decent amount onto the crank so you don't mess up the crank threads or the bolt itself. then use the puller on the back of the bolt. once it starts coming off, take the crank bolt out.

[240z4u]

Dont forget to take the crank bolt back out, else you may have to pound it out with a punch.

This is all theoretical of course LOL.

[KlanjacOFF]

haha, thanks for the info guys. You'll be getting alot of random *** questions from me in the upcoming months. got some big plans ahead
